iFi serves up micro iDSD Signature dish!

Sporting a host of enhancements both inside and out, one of the
most highly acclaimed hi-res DAC/headphone amps on the planet
just got even better – meet the micro iDSD Signature.

Since launching in 2017 as an upgraded version of the original micro iDSD, the
micro iDSD Black Label has been iFi’s top-of-the-range battery-powered
DAC/headphone amp. The new Signature edition builds on its predecessor’s
reputation for exceptional sound quality and versatility with enhanced circuitry in
critical areas and a new 4.4mm Pentaconn headphone output, among other
upgrades.

Digital Engine
Hi-res audio support is state-of-the-art, handling PCM data to 32-bit/768kHz, all
levels of DSD up to DSD512, and single- and double-speed DXD. MQA – the hi-res
streaming codec, as used by Tidal’s ‘Masters’ tier – is also supported. Thanks to the
Burr-Brown chip’s True Native design, PCM and DSD take separate pathways – this
enables DSD, as well as PCM, to remain ‘bit-perfect’ in its native form right through
to analogue conversion. This is often not the case with DAC devices from other
brands.

Extensive jitter-eradication technologies are applied to the digital engine, including
iFi’s GMT (Global Master Timing) femto-precision clock and intelligent memory
buffer. The micro iDSD Signature also comes with iFi’s GTO (Gibbs Transient Optimized) digital filter installed; alternative digital filters can be loaded as firmware
updates if preferred.

Changes

While the most obvious changes from the previous Black Label version of the micro
iDSD are the fine-tuned audio circuitry, the 4.4mm Pentaconn headphone output
and the new Space Blue finish, numerous other enhancements have been applied
to the new Signature edition.

The faceplates at the front and rear have been trimmed for a sleeker look, with a
redesigned volume knob and new switches for XBass+/3D+. A multi-coloured LED
to indicate the sampling frequency of the music being played is now also sited on
the front panel, while the IEMatch control has been moved from underneath the
unit to the side.

A USB-C charging port now resides on the right hand side, next to a new battery
status indicator. Damping feet now adorn the underside of the unit, too – it all adds
up to a range of improvements that make this the best-ever version of iFi’s much
lauded micro iDSD.
